Definitions

  • the present invention relates to a tubular element for withdrawing liquid from a container by application of a depression at one of its ends, intended to pass through an opening or conduit inlet of said container, the section of this tubular element being calibrated to be joined with the edge of this opening or with the wall of this duct.
  • sachets used more particularly for packaging of beverages, intended to allow consumption the drink directly from the sachet by pre-rising using a suction straw.
  • These sachets generally have a hygiene problem that results from that the straw can be removed and put back in the sachet, so there is a risk that the user will reintroduce a soiled straw in the packaging. This risk is all the greater as the user is very often a child and even a very small child for whom the notions hygiene can be vague.
  • the end of the straw intended to be introduced into the sachet is generally cut in a bevel thus sparing a pointed end, to allow perforate a seal intended for sealing the sachet before its first use.
  • the object of the present invention is to remedy, less in part, to the aforementioned drawbacks and risks.
  • this invention firstly relates to a tubular element of the above-mentioned type, as defined by claim 1.
  • This invention also relates to a method of manufacture of this tubular element as defined by the claim 5.
  • the bulge annular is constituted by an end portion of the tubular element of thermoformable material, inverted on itself outward.
  • the outer surface end frustoconical is then formed on the end of this portion turned over.
  • the end of the portion of the tubular element returned is brought back along the straw and forms an annular bearing outside the tubular element, serving as a stop to stop this tubular element when you want to remove your annular bulge from opening or section conduit corresponding to the normal section of this tubular element after having engaged it through this opening or this conduit.
  • the frustoconical portion formed at the front of this annular bulge allows to exert a centrifugal force on the edges of the opening or wall of the conduit formed of a material elastically stretchy to expand and allow insertion of the tubular element in the bag and the tightening of this opening or this conduit on this tubular element, after the passage of its bulge.
  • the form of execution preferred embodiment of the invention provides a means of preventing effectively removing the tubular member while at the same time solving the problem relating to the end cutting the straw, since it is turned upside down and that the new end is no longer bevelled and is no longer neither sharp nor cutting, the formation of truncated cone by hot molding on the inverted part of the tubular member producing a blunt edge.
  • the tubular element illustrated in FIG. 1 is a polypropylene straw 1 in this example, as shown commercially available, having a segment in which a bellows is formed by the formation of accordion folds to allow the straw to be bent there.
  • a end 1b of the straw 1 cut in bevel constitutes its suction end intended to be introduced into a container for packaging a drink.
  • this bevel is not necessary in the case of the present invention.
  • the other end 1c of this straw 1, through which the liquid is sucked, constitutes the dispensing end of the liquid in this container.
  • the beveled end 1b is introduced into a annular impression 2 of a first heated mold 3, in the case of polypropylene used in this example, at the temperature softening of this material which is about 140 ° C.
  • This imprint has a rounded bottom and a width slightly greater than twice the thickness of the straw wall 1.
  • the internal annular face 2a of this imprint 2 has a very slight taper, the smallest diameter towards the opening of the cavity 2 and corresponds to the internal diameter of the straw 1.
  • this second annular impression 4 is formed by a cylindrical surface internal diameter of which corresponds to the internal diameter of straw 1 and a frustoconical external surface whose small base preferably has a very slightly diameter greater than the inside diameter of straw 1, by a value roughly corresponding to the thickness of the wall of straw 1.
  • a frustoconical part 1e is formed at the front end of the annular bulge 1d ( Figure 3).
  • This range serves as a stop intended to prevent the straw 1 from coming out again after having engaged through an opening or conduit calibrated to the section of straw 1 and formed in an elastic material expandable.
  • the frustoconical part 1e formed at the front end of the bulge 1d makes it possible to dilate the material of the opening or of the calibrated conduit controlling entry into the container.
  • the material in which this opening or passage is formed must have sufficient elasticity to allow this expansion elastic, to tighten after the passage of the bulge 1c and prevent it from coming out.
  • This material can advantageously be based on polyethylene.
  • a straw was introduced according to the present invention in a sachet containing 0.5 liters of water and we made the straw penetrate 5 cm beyond the opening or of the calibrated passage. We held the straw vertically and we then dropped the bag. The 1d bulge allowed retain the bag.
  • the manufacturing process described is effectively simple and quick to implement. Furthermore, the shape described execution allows, as we have seen, not only to solve the problem of retaining a sachet filled with 0.5 liters of water, but eliminating the risk of injury that beveled straw presents. Therefore, even if we take out the straw, for example once the container is empty pulling very hard or cutting the bag, there is no risk of injury from the end of the straw was inside the bag.
